With the axis ot-the shaft ying below'the buckle line, a positive braceis formed and any effort to open the door 8;, in the direction of thearrow as (which is the only way t;

theoloor can be opened) would result merely in forcing the brace morefirmly into the floor and door. Since there are two holes 12' and twoholes 14, withcorresponding prongsi for the brace to swing around or tobe forcedaround into.theopposmg'position where it might be buckledby theopening of the door. Thus itis impossible fora person to introduce acase knife under the door to at- 0 feet the position of the brace 17vand 18 with any efl'ectiveresults.

As an ancillaryfeature, I provide We cautionary means in the nature of astaple 23 [which rides inthe portion 24 ofthemernber 1 on the members 17and 18, it is impossibleea 'trated in Fig. 2.

shown in dotted lines in Fig! 2,"the' staple 23 is withdrawn so as tooccupy thep'osition shown in dotted, line in Fig. 5. \Vhen, however, theparts are jammed down into the position shown in full line in Fig.2,-=the staple 23 is in line with the sockets 25, 25 and is pushed downinto the sockets, as illustated in full lines in Fig. 5, to form thepositive lock.

As a further precautionary feature I provide a small leaf spring 26 setin the'member 18 and engaging the member 17, as illus- The idea of thisdevice is to prevent the release of the two members by any possible playin the door. Thus, assuming the staple 23 to be out of use, it the doorshould have a slight play in the di rection of the arrow 1 it might bepossible 'to shakethe door to release the upper prongs from the holestherein. However, with the presenoe'ofthe spring 26 the member 17 ismade to follow the shaking of the door and cannot be released from theopenings in which it engages.

In 'F G I have shown a modified form of the member 17 where only oneprong is provided instead of two. It will be seen that even m'that eventthe swinging of the brace is prevented by reason of the double prongarrangement invariably on the member 18.

It will be obvious that my brace may be applied to prevent movementbetween any two parts, such as the two sashes of a win dow, as well asto prevent movement between a'door and a! floor. It willalso be "clearthat it is not necessary to employ the plates'l'l and 13 but that thedoor and floor, on the other hand, may themselves be provided with smallopenings in which the positi0n, bcingdisposed outof alinemcnt with theline of stress between the objects held, means to takeup lost motionbetween said sections and means engaging through both sections adjacenttheir junctions to prevent" accidental relative movement of the sectionswhen in holding position.

2. In combination, a pair of linked sections, the free ends-of which areadapted to impinge .upon two objects between which relative movement isprevented, said sections having engaging shoulders adjacent theirjunctiomand a flat spring carried by one of theshoulders to engage theother shoulder and prevent lost motion between the sect-ions.

In witness whereof, I hereunto subscribe my name this 4th day of AprilA. D. 1916 HARRY B. i ROBERTS.
